INDICATOR.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application filed January 21, 1907. Serial No. 353,405.

T alZ w7wm it may conccrn:

Be it known that I, HARRY M. BELL, a citizen of the United States, residing at. Houston, in the county of Harris, State of Texas, have invented certain new and usetu1 Tmprovements in ndicators; and I do hereby declare the following to be a full. c1ear, and exact description of the inventiom such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and use1ul improvements in indicators for cars, and it has particular reference to an indicator for street cars in which are embodied means for moving a be1t for displaying the namcs of the streets and means for sinndtaneously moving a belt having advertising 1natter printed thereon.

In connection with an indicator of the above type the invention aims as a primary object to provide a novel construction, combination and arrangement et parts, the details of which Will appear in the course of the following description, in which reference is had to the accompanying drawings forming a part of this specification, 1ike charneters of rcference designating similar parts throughout the several views wherein:

Figure 1 is a side clevation iHustrating the housing of an indieator constructed in accordance with the present invention, parts being indicated by dotted fines. Fig. 2 is a front clevation, the front Wall of the honsing being broken away and illustrating the mechanism contained therewithin. Fig. 3 is a perspective view of a supporting base for suchhousing. Fig.1 is a diagramrnatic view illustrating the mechanism for operating the indicating system. Fig. 5 is a front elevatien et the housing embodied in the invention, showing more particularly the manner 01: displaying printed matter through the windowsthereort. Fig. 6 is a section on the line 8 S 01 Fig. 2.

Referring specificaly to the accompanying drawings, the numeral 1 designates a supporting base which is secured to the wall of the car by means of fastening bolts or screws 2 arranged at suitabe intervals and which has formed at one side thereof a brace Wal1 3 coperating with one of the side walls et the housing above referred to, to afiord a support for the elements of the transmission gearing, the Wall 3 with this object in view being constructed with bearings 1. The base is formed 'With parallel dove-tail transverse groovcs 5. in which are received coniormable tongues (S provided on the rear Wa1l of the housings 7 and T. Such honsings are constitutcd et substantially rectangular boxes having inwardly inclined front va1ls 8 and 8 which are iormed With glass windows 5) and 9 through Which the printed n1atter on the advertising and indicator belts is displayed.

'1he side watts et the housings and the wai1 3 constitnte bearings for transverse parallcl shafts 13, 1el, and and 13, 14.- and 15. The sha:tts 13 and 1 1- and 13 and 14: are mounted adjacent to the rear wall et the housings and carry respective winding reels 16 and 17, and 16 and 17. The shafts 13 and 11 project through the inner side Wall of the housmgs 7 and 7 and are provided with splines 11 Which engage in grooves 12 in the respective shaits 123 and 14. In like 1nanner the shatts 15 and 15 which are disposed adjacent the front walls 8 and 8 carry spools 18 and 18 which constitute guides for the respective indicator and advertising belts 19 and 20, the latter being wound about the respective pairs of reels 16 and 17 and 16 and 17 and having parallel movemcnt. The shafts 13 and 141 have fast oonnection adjacent one end thereoi with the liubs et bevel pinions 21 and 22. Thcse pinions are et the saine size and are in 1nesh with si1nilar superposed pinions 23 and 21 which are carried upon a vertical shaft 25. It is to be noted that the pinions 23 and 21 are dispesed similarly, whereby the shafts 13 and 14: will be rotated in the same directions upon rotation et the shatt 25 in either direction.

The shat't 25 is journaled in suitable bear ings and its 1owcr end is projected beneath the floor 26 0:1 the ar. On the pr0jecting end ozt' the shaft 25 is a beve1 pinion 27 which is in mesh with a similar pinion 28 providcd upon the inner end of a 1ongitudinal horizontal shaft 25), the latter beinp journaled in depending bracket bearings 30 and carrying at its -front end a beve] pinion 31 which is driven 'l'1'0in a similar pinion 32, provided on the lower end et a vertical shat't 33, mounted in suitab]e bearings and extending through the floor 2G.

i(.liiii the casino; is an indicating mechanism corresm nding to the indicating mechanism shown in Fig. 2, and with which the shaft 33 coiiperates, and to actuate the said mechanism there is provided a manually operable crank handle 40.

By virtue of the provision of the two housings 7 and 7 and the connections between the reels 16 and 17 of the housing 7 and the shafts 13 and 14 of the housing 7 it is obvions that the elements of the last named lionsing are operatively connected With the elements of the first honsing and that the said lionsings may be removed and interchanged with other honsings in which the belts are printed with other matter xvith- 0ut disturbing the arrangement of the operating elements.

An indintor constrncted in accordance with the present invention is simple, comparatively inexpensive t0 manufacture and practical and eflicient in use.

From the foregoing description, it xvill be seen that simple and efficient means are provided for accompliehing the objecte of the invention, but while the elements herein shmvn and described a e Well adapted to serve the .unctions set forth, it is obvions that varions 1ninor changes may be made in the proportions, shape and arrangement of the several parts, withont departing from the spirit and scope of the invention as defined in the appended daim.

Vhat is claimed is:

In an indicator of the type set f0rth, a base for attaclnnent t0 a wall, a vertical brace Wall mounted at one end of said base,

said brace wall being formed with openings, said base being formed with a horizontal dove-tail groove extehding between the ends thereof, two honsings arranged side by side and each formed on their rear walls with tongnes engaging said grooves, one of the honsings bearing against said brace wall, said housings each having their side walls forrned with openings alined with the openings in said brace wall, upper and lower shafts journaled in the openings of each housing, the upper shafts having their adjacent ends keyed and the lower shafts having their ends similarly keyed, pinions carried detachably npon the ends of the upper and lower shafts of the honsing that bears against the brace wall, said pinions having their hnbs disposed in the openings in said brace Wall, gearing for driving said pinions at the saine time and in the same direction, nppcr and lower winding reels carried by said respective upper and lower shafts, and display belts trained over the respective pairs of npper and lower reels, said housing;s having their front walls provided. with openings to permit of reading said display belts.

In testimony whereof, I aflix my signature, in presence of two witnesses.
